Pearl Jam’s Eddie Vedder continued his recent string of on-stage guests spots in San Francisco on Wednesday night, joining Kings of Leon for a performance of “The Bucket” from the latter’s 2004 album Aha Shake Heartbreak. If you’re wondering why these guys were in the same room, it’s because Oracle paid PJ and KoL lots of money to play their Oracle Appreciation Event.

This latest guest spot follows Vedder’s recent appearances at Tom Petty’s concert in Amsterdam, Bruce Springsteen’s back-to-back shows at Wrigley Field and The Gaslight Anthem’s set at DeLuna Fest. He and his band were also joined by Jay-Z during their headlining performance at last month’s Made in America Festival.
